Perfect for comfortable street driving or the firm handling of a more modern sports car
Shock Mount Type:

Stud Type Upper Mount

T-Bar Type Lower Mount

*Notes: Some front applications may require the lower a-arm to be dropped for installation. Body diameter may be too large to allow mounting from the bottom. Some control arm's shock openings may need to be enlarged to accept a QA1 shock.

Stud mounts are measured to the shoulder of the stud. Add 13/16'' for installed compressed length per stud mount. Loops and t-bars are measured to the center of the loop. Lengths may vary slightly.

QA1 Single Adjustable Pro Coil Systems are great options for anyone looking for fully adjustable ride height and valving control while maintaining stock configuration control arms. Choose a spring rate that fits your driving style and adjust the valving to match, and you're on your way. This system is a great option for anyone looking for a suspension upgrade for their street car. With 18 valving options of simultaneous compression and rebound adjustment, the QA1 Single Adjustable Pro Coil System allows for that soft comfortable ride you want when cruising and the firm handling you'd expect from a more modern sports car.Made in the USA

The Pro Coil System includes:

Two Proma Star single adjustable coil-over shocks

Two specially designed conical springs

All mounting hardware.

Easy Bolt-In Installation - Minimal modifications to be made. Remove the existing shocks and springs and the QA1 Pro Coil System bolts right back in.

Specially Designed Conical Springs - This spring is designed so that the lower end sets on the coil-over shock and the upper end sets in the original spring bucket in the frame. This allows for the use of a longer and lighter spring for
more stored energy, offering increased weight transfer. Greater
durability is also achieved by locating the spring pressure in the frame
and not on a single stud.
